Hi

I am connected to a Gigabit Network through a Gigabyte switch. My Network card is Gigabyte and I am using Cat6 cables.

My Network connection is topping out at exactly 100mb/s

How can I find the bottleneck here.

Is there a good bit of software to find this or a good technique. I have tried all the no brainers like cables etc.

Really appreciate any help.

Would like to know about the Nexus 5672 UP switch port density.
I understand that it has 48 fixed ports which can support 10 Gbps Ethernet.

Would like know in addition to that can it support additional 16 ports of 10 Gbps Ethernet.
I gone through the data sheet but i would like to clarify it.

Hi,

Please am trying to trace a port as shown below

sh arp | i 10.111.10.156
Internet  10.111.10.156           1   0003.e371.e0c1  ARPA   Vlan200

sh mac address-table | i 50c1
  200  0003.e371.e0c1   dynamic  Yes         15   Po42

As you can see, i have the arp/mac  result,

I know if it was another physical interface e.g gi1/0/1.

i can just use sh cdp to that interface.

But i don't know  what  to do with port channel

Thanks for your support.

Overview:
 
We are trying to implement dual ISP on an ASA 5510 running 8.2(5)55 in an active/standby capacity. The primary goal is to protect the MS Exchange environment for inbound and outbound mail and protect user access to the internet.
 
For mail traffic to EX 1 and EX2:
 
Currently inbound and outbound traffic on the AT&T (outside) connection works as designed doing a 1:1 NAT to each of the EX servers.
 
Currently inbound traffic on the Verizon (backup4G) connection works as designed doing a 1:1 NAT to each of the EX servers.
 
Currently outbound traffic from the EX servers going to an outside host that is routed out the backup4G connection does not seem to work and looks like it is getting double NAT’ed. (Packet Tracer Below)

Hi experts,

I was wondering if anyone could help me please?

I have inherited a network with Cisco WAP 561's. I was asked to configure a second SSID for a guest network which completely separated the guest clients from the main LAN.

For testing I placed a Cisco RV230 between the WAP and the LAN. I then created a second SSID and assigned it the VLANID 25. I set the RV230 to serve DHCP requests to VLAN25 only and act as a router. Requests from the Private SSDID on VLAN 1 are simply ignored and passed to the main network - which is also connected to the LAN port on the RV230.

This worked perfectly.

But....

All the WAP561's have been connected and powered by Netgear GS108PE POE switches. With these switches inbetween the Cisco Rv230 and the WAP the private SSID works perfectly but the guest clients do not receive DHCP requests. I cannot work out why.  I note if i set a static IP on the guest network it works fine.

I am hoping there is a setting on the router I am missing.

I have created a VERY BASIC network diagram which I hope supports the above.

Many thanks!!

Hi,
I have a UTM in an accommodation building that does our web-filtering, advanced threat, IPS, application control etc and the CPU maxes out badly during peak hours. I checked the CPU and it is an Intel Celeron. I checked the concurrent connections and the maximum was around 500,000 and the average for the day was 25,000. According to the datasheet of the current UTM, it can handle 4 million concurrent connections. This is not true.

I need a new UTM that can easily handle the current maximum load plus an increase of 20% per year for three years. Running all the UTM features will also increase the load on the CPU, so the new UTM needs to be able to handle the load of potential 500,000 concurrent connections plus an annual 20% increase.

I am asking because just looking at a datasheet is not accurate. My UTM states on the manufacturer's website that it can handle 4 million concurrent connections. But it clearly can't.

From your own experience, what are the best models (with a really good processor)  I should be looking at?

Hello Experts,

I would like to know how can I enable IP tracking on Dell 6224 POWER CONNECT switches. I am going to do an upgrade and I have mapped the vlan information but I am not sure what is connected to the ports.

Can anyone show me how to enable ip tracking on these switches. If these switches don't support IP tracking like Cisco ones can u suggest a software I can use to map out the IPs that are connected to these switches.

Thanks,

Having issues logging into a Cisco WAP121 wifi access point. I'm using a direct ethernet cat5 connection from the nic card of my computer directly into the single ethernet jack on the back of the access point. I enter the default address of 192.168.1.245 into my browser but it never pulls up the config landing page.

The ethernet card in the computer has its TCP/IP v4 all set to automatic (obtain IP address & DNS).

The access point has been reset to default prior to doing this. Also I've tried multiple machines, multiple WAP121 AP's, multiple web browsers, brand new ethernet cables, Macintosh laptops...ect.

One odd thing to note (in the attached image). If you look up at the top of the Chrome browser, the tab for that page has the "Cisco" icon in it. So where is it getting that image from, the router? And if its getting that from the router, why isn't the landing page coming up? Also after I enter the address and hit enter, the "admin.cgi?action=main" auto populates the address bar. page.png

What is the minimum recommended distance between Transformers or 600 volts power cables should servers be installed?

We need to move our backup appliance and one option is inside our electrical room.    I know you should keep data and power cords apart but what about transformers and big 600v power cables?

Thank you for any insight you can offer.

Is there a way to remove two factor authentication, such as the console port serial connection, on a Fortinet Fortigate 80D? Does twio  factor authentication apply to the serial console port also?

I clicked activate via SMS, but before getting a text I clicked apply to the two factor (muscle memory I guess -  must click apply! lol), and now cannot get into the web gui of the device due to it asking for a token. No other users for me to utilize.

I have 2 controllers 2 5500 Series.  I have the software upgraded to 8.0 however, I still don't have the management software yet.  I don't know when it's going to be approved.  The bigger problem is I have about 10 AP that I need to install by Monday.  I can't SSH into the AP it tells me connection refused and network error.  I can't even direct connect to the AP because I don't know if this has a default IP on it. Is there anything I can do to get these AP set up????

I'm taking over an environment that has a half a dozen Cisco routers if various makes and models, mostly Cisco 1800 series integrated services routers.  We're not sure what they are all doing and we believe that most of them are unnecessary equipment hanging around from the past.

We don't know the passwords to any of the routers.

I have a rough idea of the procedure for recovering the password in Cisco IOS, by using a terminal cable and breaking into ROMMON mode at boot up.

However, I'm concerned about what if the running-config of the router has not been saved by the last person who was working on it? These routers have been online for months, maybe years, and I'm afraid to reboot them.

So is there a way to do either of the following:

1) See the running-config of the router without knowing the password so I at least have a rough idea of what this router is doing in the event that I have to reconfigure it from scratch ?

2) Determine if the startup-config and running-config are different, without knowing the password or rebooting the router ?

Hi all,

Im looking for a network load balancer for Exchange server as virtual VMWare appliance.

Typically it is just layer 4 but if it can do later 7 that'd be great.can anyone here please share some thought and comments regarding VMWare NSX, Citrix Netscaler and Brocade SteelApp ?

Which one is better and the best for virtual exchange server 2013 or 2016 ?

Thanks.

Following on from my various other questions on the subject of Networking my home, as we're doing a new install network run around the place, what distance should I aim to keep my ethernet cables away from the mains wiring under the floors etc.

My node zero room server room is shown in blue on the following link in the plan.  As you can see its not near the main fuse board (coloured red in the cloakroom in the front).  However, there will be a lot of sockets in the node zero room, I'm guessing around 8 double sockets at differing heights and on different sides of the 3 walls.  Will this be an issue for interference etc?

I'm looking for some guidance on the network configuration for connecting two locations, each is on different subnet. These locations were recently connected via Ubiquiti AirFiber 5 wireless bridges. The bridge is up and working perfectly. Prior to this the sites were connected by VPN.

The problem is two different subnets, and all traffic is currently passing thru the firewalls at each site. The only way I could get the two subnets to talk to each other was to put a secondary IP address (of the other subnet) on the firewall (default gateway) at each location. I believe this is a form of multi-homing the networks. When a device at site 1 tries to contact a device at site 2, it goes to the default gateway (firewall), because of it's secondary IP, it says stay here. I don't believe this is the right way to set this up, because all traffic is passing thru the firewalls.  How should this be setup?  (We need to keep the two subnets.)

Site 1
10.0.1.0/23
WatchGuard Firewall & (default gateway): 10.0.1.1 (Secondary IP: 172.16.1.3)
AirFiber: 10.0.1.2

Site 2
172.16.1.0/23
WatchGuard Firewall (default gateway): 172.16.1.1 (Secondary IP: 10.0.1.3)
AirFiber: 172.16.1.2

Thanks.

We have 2 domains in the school network. Domain 1 has a super MFP that we need to access in domain 2. I have installed a wireless NIC into a client PC in domain 2. I can then connect to the printer in domain 1 (I don't need to access any further domain services - only the printer). It does work but seems to confuse internet browsing and name resolution. What can I do to ensure that this is set up correctly?

Hi All,

I have two Netgear GS724T v2 devices, 2 SFP modules and a 30m LCLC optical cable which I would like to use to connect two switches together but I am having massive issues - Probably because I am a noob!

I have 3 switches in total (all GS724T) and have 2 connected via Ethernet with vlans trunked and this is working perfectly. However I want to connect the third switch via fibre using the SFP modules but cant seem to figure out to configure this. I am reading up on LAG but I cant see how to trunk and get the two switches communicating.

In the crudest form, Ports 1, 2, 3  and 4 will have different vlans configured on them. The SFP module (port 25 (even though its a 24 port switch)) should be trunked with vlans 1, 2, 3, 4.

Any help?

Thanks in advance

I have taken on a new client of which is moving office locations, but is using the same ISP.  The ISP will assign them new IP information.  I am not too familiar with Juniper products, and I simply want to make sure when I change the IP address it works fine, etc.  The IP information that will change is the actual IP address and the Gateway.  The subnet mask, DNS Servers, and the internal network IPs and port forwarding all remain the same and should "note" be changed.  This client hosts Exchange, OWA, SharePoint, VOIP, and VPN resources, so there is port forwarding going on.

I SSG5 hardware version is 710(0), and firmware version is 6.3.0r2.0, and I backed up the config as well.

I found the below link on the net that's pretty descriptive on how to accomplish this, but I do have questions that need to be clarified:

Steps 1 thru 4 are pretty straight forward.  The assigned subnet mask is 255.255.255.224, so the IP will be entered as 68.?.?.?/27
Step 5:  I am assuming when I change address as described in step (4),  it ought to display the changed IP address within the VIP - IP Address, and not require me to select Edit which is displayed to the right of it?
Step 6:  I take this step is necessary since I cannot modify the entry, and it will not dynamically update the gateway information.  I just want to double check and ask if this step is actually required or has changed.  
Step 7:  I can see the IP Address/Mask needs to be 0.0.0.0/0, untrust-vr selected, and …
